Seconds From Disaster S02E04
Heather was driving along the road in Bumpy Island, singing to a song by Ed Sheeran. Later on above the mountains, Jonathan began to pull Mark's truck up the hill, however the chain snapped as Mark's truck slides down the hill. The tanker trailer dangles off a cliff. Mark was relieved his truck did not go over the cliff. However, the tanker trailer from Mark's truck detached and tumbled down the mountain. Heather was driving on the road below until she gets hit by the tumbling trailer. Heather surprisingly suffered only minor injuries.
